I think what Marko means is that there is a textual way to represent
Python source code, and there are multiple files that represent
identical Python programs, hence "noncanonical". If you have two UTF-8
encoded files that contain the same text, they will have the exact
same bytes in them, because UTF-8 defines a canonical byte
representation for text. You can't say that about Python source.
